SIDEHILL-PLOW.

mamas.

To all whom it may concern:

Be it known that I, Ronnnr F. STUBBLE- FIELD, a citizen of the UnitedStates, residing at Enterprise, in the county of VVallowa and State ofOregon, have invented a new and useful Improvement in Sidehill-Plows, ofwhich the following is a specification.

This invention relates to plows and its general object is the provisionof a plow adapted to be used in plowing land too steep for working withordinary plowvs, which plow is so constructed that it is adaptedfor useon Varying slopes and particularly adapted for immediate changes whilein operation so that the plow may be changed to suit the immediate slopeit is working on.

A. further object of the invention is to provide a simply lconstructedand easily handled side hill plow particularly adapted for turning afurrow one way down a hill, the plow share being adjustable at any timeto suit varying slopes of the land along the line of the furrow.

It is a further object of the invention to provide a plow wherein theplow standard which carries the share is rotatably mounted upon the beamso that the plow standard and share may be turned in opposite directionsinto an angle with the plow beam or so that the share may be turned withits line of operation parallel to the plow beam so as, in the lattercase, to divide the plowed ground each way from the center of thefurrow, the plow under these circumstances being particularly adaptedfor use in the construction of water ditches either for irrigating thedrainage or the construction of ditches in which pipes are to be placedor for cultivating vegetables, etc.

Another object of the invention is the provision of a device for holdingthe plow standard and share in their angularly adjusted positions, thisdevice being capable of being operated either by hand or the foot of theplowman; and another ob ect is to provide for removable and ad ustablefurrow cutters disposed in advance of the share.

Other objects will appear in the course of the following description.

Specification of Letters Patent.

Application filed. June 1'7, 1916. Serial No. 104,264..

My invention is illustrated in the accompanying drawings, wherein:

Figure l is a side elevation of a plow con structed in accordance withmy invention;

Fig. 2 is a section on the line 22 of Fig. 1;

Fig. 3 is a perspective view of the notched bar 18;

Fig. tis a perspective detailed view of the cap 341;

Fig. 5 is a section on the line 5-5 of Fig. 1, showing the plow adjustedwith its share in line with the beam;

Fig. 6 is a like view to Fig. 5 but showing the plow adjusted with itsshare out of line with the beam; and

Fig. 7 is a fragmentary side elevation showing a slightly modified formof the construction.

Referring to these drawings 10 designates the plow beam to the forwardend of which is connected the usual clevis 11 and to the rear end ofwhich is attached the usual upwardly extending handles 12 braced fromthe beam in any suitable manner. Extending downwardly from the underside of the beam is a plow standard 13 which is rotatably connected tothe beam by means of a vertical pivot bolt 14: which passes through thebeam. This standard 13 is rotatably shifted by means of a handle 15whose end 16 is bifurcated to a brace or standard and is pivoted theretoby bolts 17 The lever 15 opcratively engages with certain notches formedin the upper face of a bar 18 which is supported by means of the legs 19bolted to the rear end of the plow beam. The lever 15 is urged downwardinto engagement with the notches by means of the coil spring 20 which,at its lower end is connected to an upwardly extending eye 21. Mountedupon the face of the standard 13 is a plow share 22 having the form ofthe usual shovel cultivator share, this share being held in place uponthe standard in any suitable manner as by the bolts 23. The standard 13is braced from the beam by means of the upwardly and forwardly extendingbrace rod 2 1 which at its upper end has a nut which engages theabutment 25 and which at its lower end is provided with a hook-shapedterminal which engages a transversely elongated eye 26, shown mostclearly in Figs. 5 and 6. This eye is operatively connected at itsendsto a ll-shaped band 27 engaged withatr'ansverse bar 28 bearingagainst the rear face of the standard. Disposed in advance of thestandard 13 are cutters 29 defining the edges of the furrow. Thesecutters at their upper ends are inwardly turned as illustrated in Fig. 2and haveupwardly extending shanks 30 which pass through an. opening in aplate 31 which plate passes beneath the beam 10. At the upper ends theshanks 30 are connected by means of a transverse bolt 32. It is obviousthat the cutters may be shifted longitudinall'y along the plow beam andthereby adjusted nearer to or farther from the plow share. I

. The contacting faces of the standard 13 and the plow beam areprotected by wear plates 33 and 34;, one wear plate 3 1 having the formof a'cap as illustrated in Fig. 1 and being bolted to the upper end ofthe standard, whilethe wear plate 43 has the form of a channeliron andis'bolted to the beam.

In Fig. 7 I show a slightly modified form of this plow inwhich the lever15 which is connected to the standard 13 in the same manner asheretofore described is drawn upward by a spring 20 and engages withthe'b'ar 18 which is notched on its under face. In Fig. 1 the lever 15may be operated by the plowman lifting up upon the lever and laterallyshifting it, while in Fig. 7 the lever 15 may be operated by the foot ofthe plowman.

QIt will be seen that the plow constructed as above described isparticularly adapted toworking on side hills by reason of the fact thatthe angle of the share with relation to the plow beam or the line ofdraft may be readily changed so as to hold the plow to its work,notwithstanding the tendency of the plow to work down hill. Thistendency is counteracted by the angular disposition of the share,and-this angularity of the share may be changed or adjusted at any timeto suit the varying inclinations of the ground. It is plainthat on thecompletion of the furrow and the turning of the plow so as to move inthe opposite direction, the lever maybe shifted to an opposite positionin the notched bar 18 which places the plow in condition for turning thefurrow exactly as when moving in the first named direction along theunplowed land. It is obvious also that on level land, the standard maybe rotated to shift the angle of the plow share so as to cause the plowtothrow the dirt toward one side or the other. By placing the lever.

in the middle of the notched bar however, the pl'ow'may be usedforturning the earth ways from the middle of the furrow,

which makes the plow particularly adaptable to the opening of waterditches for further noted that the adjustment of the plow standard maybe made at any time while the plow is moving'so that the plow is at alltimes under the control of the operator.

\Vhile I have illustrated what I deem to be the most effective form ofmy improved plow, I do not wish to be limited to all of the details ofconstruction as it is obvious that these may be modified in many wayswithout departing from the spirit of my' in vei'ition. it
